Package : proftpd-dfsg
Version : 1.3.5e+r1.3.5-2+deb8u7
CVE ID : CVE-2020-9273
It was discovered that there was a regression in a previous fix for a
use-after-free vulnerability in the proftpd-dfsg FTP server.
Exploitation of the original vulnerability within the memory pool handling
could have allowed a remote attacker to execute arbitrary code on the
affected system. However, the fix that was released in proftpd-dfsg
version 1.3.5e+r1.3.5-2+deb8u6 had a regression around the handling
of log formatting.
For more information, please see:
https://github.com/proftpd/proftpd/issues/903
For Debian 8 "Jessie", this issue has been fixed in proftpd-dfsg version
1.3.5e+r1.3.5-2+deb8u7.
We recommend that you upgrade your proftpd-dfsg packages.
